This is your first biology unit- healthy bodies. We will be going through at quite a rush, so do try to keep up. Use the website to review what you cover in class. I’d like to say any mistakes in these aren’t my fault, but I am trying to correct some!
Most of this work was produced by the Biology Department, so most questions would be better directed to them. The glossary isn’t complete but I will try to update it as we go through the course.

Effect of Exercise on Heart Rate This is a practical sheet for you to go through to find out how exercise affects your heart rate. One of the S1 asked the difference between affect and effect- affect is almost always used as a verb, while effect is usually used as a noun. There, I hope that has cleared that up.
All living things
Remember ‘MRS GREN’ – the first letter of Mrs Gren gives one of the characteristics
Movement – they can move and change their position.
Respiration – they can create chemical reactions that break down nutrient molecules in living cells to release energy.
Sensitivity – they can detect or sense stimuli and respond to them.
Growth – they can permanently increase their size or dry mass by increasing the number or size of their cells.
Reproduction – they can make more of the same kind of organism as themselves.
Excretion – they can excrete toxic materials, waste products of metabolism, and excess substances (note that excretion is not the same as egestion).
Nutrition – they can take in and absorb nutrients such as organic substances and mineral ions. These nutrients contain the raw materials or energy needed for growth and tissue repair.

Below is a table showing the 10 major organ systems in the human body, giving the function and the major organs.
The human body is made up of several organ systems that work together as one unit. Organ systems fit between the hierarchical levels of organs and the organism. Ten major organ systems of the body are listed below along with several organs that are associated with each system. It is important to keep in mind that these organ systems don’t just exist as individual units. The final product of these cooperating systems is one unit called the body. Each system depends on the others, either directly or indirectly, to keep the body functioning normally.
|1. Circulatory System||The main function of the circulatory system is to transport nutrients and gasses to cells and tissues throughout body. This is accomplished by the circulation of blood. Two components of this system are the cardiovascular and lymphatic systems.||Cardiovascular: This system is comprised of the heart, blood, and blood vessels. The beating of the heart drives the cardiac cycle which pumps blood throughout body. Cardiovascular organs: heart, blood vessels, blood Lymphatic: This system is a vascular network of tubules and ducts that collect, filter, and return lymph to blood circulation. As a component of the immune system, the lymphatic system produces and circulates immune cells called lymphocytes. Lymphatic organs: lymph vessels, lymph nodes, thymus, spleen, tonsils|
|2. Digestive System||The digestive system breaks down food polymers into smaller molecules to provide energy for the body. Digestive juices and enzymes are secreted to break down the carbohydrates, fat, and protein in food.||Primary organs: mouth, stomach, intestines, rectum|
|3. Endocrine System||The endocrine system regulates vital processes in the body including growth, homeostasis, metabolism, and sexual development. Endocrine organs secrete hormones to regulate body processes.||Endocrine structures: pituitary gland, pineal gland, thymus, ovaries, testes, thyroid gland|
|4. Integumentary System||The integumentary system protects the internal structures of the body from damage, prevents dehydration, stores fat and produces vitamines and hormones.||Integumentary structures: skin, nails, hair, sweat glands|
|5. Muscular System||The muscular system enables movement through the contraction of muscles.||Structures: muscles|
|6. Nervous System||The nervous system monitors and coordinates internal organ function and responds to changes in the external environment.||Structures: brain, spinal cord, nerves|
|7. Reproductive System||The reproductive system enables the production of offspring through sexual reproduction. It is comprised of male and female reproductive organs and structures which produce sex cells and ensure the growth and development of offspring.||Male organs: testes, scrotum, penis, vas deferens, prostate Female organs: ovaries, uterus, vagina, mammary glands|
|8. Respiratory System||The respiratory system provides the body with oxygen via gas exchange between air from the outside environment and gases in the blood.||Respiratory organs: lungs, nose, trachea, bronchi|
|9. Skeletal System||The skeletal System: This system supports and protects the body while giving it shape and form.||Structures: bones, joints, ligaments, tendons, cartilage|
|10. Urinary/Excretory System||The urinary/excretory System removes wastes and maintains water balance in the body.||Structures: kidneys, urinary bladder, urethra, ureters|
Here is a table containing a glossary of terms for your Biology Topic 1- Healthy Bodies
|Term||Meaning / Definition|
|amniotic fluid||The fluid which surrounds the foetus whilst it is in the womb. It protects the foetus and allows the exchange of water, nutrients and other biochemical products.|
|Biology||The study of life. Biology is the science of learning about every kind of life|
|cardiovascular system||the body system that contains the heart and blood vessels. This system transports nutrients around the body.|
|cell membrane||controls what goes in and out of the cell|
|Cells||Cells are the basic structural unit for all organisms. They can usully only be viewed with a microscope and consists of cytoplasm and a nucleus enclosed in a membrane.|
|chromosomes||A thread like stucture made of DNA and found in the nucleus of most cells.|
|clinical thermometer||an instrument for measuring body temperature.|
|contractions||Contractions start when the female goes into labour. They cause the upper part of the uterus to tighten and the lower part to relax, this helps move the foetus into the birthing canal ready for delivery.|
|cytoplasm||where chemical reactions occur in the cell|
|diaphragm||a muscle and fibrous tissue used in respiration. When breathing in, the diaphragm contracts and moves down, thus enlarging the volume of the thoracic cavity allowing air to be drawn in through the nose and throat. The opposite occurs during expiration (breathing out)|
|eyepiece||the part that you look down on a microscope. It contains a lens which helps enlarge the image.|
|fallopian tube||tube connecting the ovary to the uterus, where fertilization occurs|
|Fertilisation||is the joining of the egg and the sperm to form a zygote (fertilised egg). Fertilisation occurs when the nucleus of a sperm fuses (joins) with the nucleus of an egg. This happens in the oviduct (fallopian tube)|
|focussing wheel||A means of moving the specimen closer or further away from the objective lens to render a sharp image. On some microscopes, the stage moves and on others, the tube moves|
|foetus||the young of an animal when it is still in the womb or egg but in the later stages of development|
|health triangle||Three aspects of health, physical, mental and social|
|heart rate||This is the speed which your heart beats at, measured in beats per minute. Your heart rate can change depending on what you're doing e.g it increases when you perform physical exercise and decreases when you are sleeping.|
|homeostasis||Body responses to external and internal stimuli to maintain stable conditions|
|labour||The process of the mother giving birth to her young.|
|light source||A way of making the stage brighter to illuminate the specimen.|
|lungs||The main organ which allows mammals and some fish to breath.|
|magnification||making an object appear larger due to a microscope. It is calculated by multiplying the magnification of the eyepiece by the magnification of the objective lens|
|mammal||Warm blooded animals with a backbone whose young feed on their mothers milk.|
|microscope||an instrument for viewing small objects such as cells|
|nucleus||contains the DNA organised in chromosomes|
|organs||Many tissues come together to form an organ.|
|oviduct||another name for the fallopian tube|
|physiological||the branch of biology that deals with the normal functions of living organisms and their parts|
|placenta||An organ which develops in the uterus during pregnancy. Oxygen and glucose are passed from the mother’s blood to the foetal blood, and carbon dioxide and other wastes are passed from the foetal blood to the mother’s blood.|
|pulsometer||an instrument for measuring pulse rate|
|respiratory system||the body system that allows us to breathe|
|sphygmomanometer||an instrument for measuring blood pressure|
|stage||The small platform on the microscope where you place your specimen to examine|
|systems||several organs working together for one purpose|
|tissue||A tissue is part of an organism consisting of a group of cells having a similar structure and function|
|trachea||Connects the mouth to the lungs to allow air to pass through, also known as the windpipe|
|ultrasound||High frequency sounds above the upper range of human hearing, used to check on the health of a growing foetus.|
|umbilical cord||The cord which attaches the mothers placenta to the foetus via the belly button. This allows the mother to pass oxygen and nutrients to the feotus, whilst also allowing the foetus to pass carbon dioxide and other waste to the mother|
|Zygote||A fertilised egg. The zygote is the earliest developmental stage after fertilisation and contains the combination of the DNA from both parents.|
