foundations of biology and cells
This term refers to the study of living things.
What is biology?
These four basic tissue types make up the human body [need to name all four!!!!]
What are epithelial, connective, muscle, and nervous tissue?
These four lobes make up the cerebrum: frontal, parietal, temporal, and this.
What is the occipital lobe?
These cells carry oxygen and have a lifespan of ~120 days in adults.
red blood cells
This gas makes up about 21% of the air we breathe and is essential for cellular respiration.
What is oxygen?
These are the basic characteristics shared by all living things, including growth, reproduction, and response to stimuli.
What are the characteristics of life?
These are the four major classifications of bones: long, short, flat, and this final category.
What are irregular bones?
This insulating layer around neurons speeds up nerve impulses.
What is the myelin sheath?
Plasma, red blood cells, white blood cells, and platelets make up this bodily fluid.
What is blood?
These chemical messengers travel through the blood to regulate body functions.
What are hormones?
This widely accepted theory states that all living things are made of cells, and all cells come from preexisting cells.
What is the cell theory?
This type of bone marrow makes blood cells; the other type stores fat.
What is red bone marrow? (yellow stores fat)
These electrical signals travel down a neuron to transmit information.
What are nerve impulses (action potentials)?
People with this blood type are universal donors because their RBCs have no A or B antigens.
What is type O?
This deadly gas binds to hemoglobin more strongly than oxygen, preventing oxygen transport.
What is carbon monoxide?
This molecule type forms the main structure of cell membranes, with a hydrophilic head and hydrophobic tails.
What are phospholipids?
This happens to joints when the cartilage wears down, causing pain and reduced mobility.
What is arthritis or joint degeneration?
This lobe is primarily responsible for vision processing.
occipital
This term describes the amount of blood pumped by the heart per minute.
What is cardiac output?
This pathway describes how urine travels from kidneys → ureters → bladder → urethra.
What is the urinary tract pathway?
This monosaccharide is the main energy source of the cell and the breakdown product of carbohydrates.
What is glucose?
Muscles work in this type of paired relationship, where one contracts while the other relaxes.
What are opposing (antagonistic) muscle groups?
This part of the nervous system sends signals to muscles to initiate contraction.
What are motor neurons?
This system returns excess fluid to the bloodstream and contains organs like the spleen and lymph nodes.
What is the lymphatic system?
These paired organs maintain homeostasis by regulating blood pH, water balance, and waste removal.
What are the kidneys?
