"Life"
The study of how our body parts work is called?
Physiology
Smallest unit of life where all the chemical processes that keep us alive occur
Cell
A group of similar cells working together to perform a specific function is called?
A tissue
All human cells (except for eggs & sperm) divide by:
Mitosis
Consists of the skin, mucous membranes, hair, and nail
Integumentary System
What is one requirement for human life?
Oxygen
Nutrients
Temperature
Pressure
Control center of the cell
Nucleus
Tissue that lines most body surfaces
Epithelial
Sperm & egg cells divide by:
Meiosis
Enables movement of the body and internal organs
Muscular system
What is homeostasis?
The maintenance of a stable internal enviroment.
Holds the cell together and acts as a gatekeeper
Cell Membrane
Tissue that has the unique property of contraction, which causes movement
Muscle tissue
The result of mitosis is:
2 new, genetically identical, cells
Consists of glands that control many of the body's activities by producing hormones.
Endocrine System
A system for when something gets out of its normal range and the body responds to try to get the situation back to normal
Negative feedback loop
Produces ATP for cell cellular energy
Mitochondria
The main function of this tissue is to connect tissues and organs
Connective tissue
The result of meiosis is:
4 new cells, each with half the original amount of genetic information
Cleanses the blood. Rids the body of wastes. Maintains salt and water balance.
Urinary System
What is an example of a negative feedback loop?
Temperature control, Blood sugar control, Blood pressure
There are 5 cell functions. Name at least one.
-Energy production
-Making & transporting proteins
-Getting rid of waste
-Dividing & producing more cells
-Building tissues
Tissue that carries electrical messages
Nervous tissue
Meiosis OR mitosis: Which involves ONE cell division
Mitosis
Composed of a network of vessels, ducts, nodes, and organs. Provides defense against infection.
Lymphatic System
