TEAS TEST
Arteries carry blood away from the heart
Veins Blood vessels that carry blood back to the heart
Capillaries single layer of endothelium that form a network that connect arteries to veins in
tissues
Pulmonary loop carries deoxygenated blood from the right ventricle to the lungs and returns
oxygenated blood to the left atrium
Systemic loop carries oxygenated blood from the left ventricle to the body, returning
deoxygenated blood to the right atrium
Systole Contraction of the heart
Diastole Relaxation of the heart
What makes the "lub" sound? atrioventricular valves closing (mitral and tricuspid valves)
What makes the dub sound? closing of semilunar valves
What controls heart contractions? Pacemaker - called the sinoatrial node
Plasma clear pale yellow component of blood that carries red blood cells, white
blood cells and platelets throughout the body.
Hemoglobin The protein in red blood cells that carries oxygen from the lungs to the rest of
the body
Lymphocytes The two types of white blood cells that are part of the body's immune system:
B lymphocytes form in the bone marrow and release antibodies that fight
bacterial infections; T lymphocytes form in the thymus and other lymphatic
tissue and attack cancer cells, viruses, and foreign substances.
white blood cells granulocytes (basophils, eosinophils and neutrophils) agranulocytes
(monocytes and lymphocytes)
macrophage a large white blood cell that ingests foreign material
Leukocytes white blood cells, which protect the body again disease
Which heart chamber pumps blood toward the lungs right ventricle
, TEAS TEST
Blood flow through the heart
What two chambers of the heart have thicker walls? Ventricles use a large amount of pressure to push blood to different parts of
Why? the body. This puts quite a bit of force on these chambers, require them to be
thicker.
Function of the digestive system break down food for absorption and distribution of nutrients to the rest of the
body
What controls the mechanical digestion and movement the parasympathetic nervous system
of food through the digestive system
What absorbs the nutrients in the digestive system? Blood vessels located along the stomach and small and large intestines absorb
digestive nutrients
What is mechanical digestion? Physical breakdown of large pieces of food into smaller pieces
Peristalsis Involuntary waves of muscle contraction keep food moving along in one
direction through the digestive system.
Chyme the semifluid mass of partly digested food that moves from the stomach to the
small intestine.
Pepsin Enzyme that breaks down proteins in the stomach
small intestine The part of the GI Tract between the stomach and large intestine that includes
the duodenum, jejunum, and ileum, where digestion and absorption of food
occurs
Hydrophilic water loving
large intestine The last section of the digestive system, where water and salt is absorbed from
food and the remaining material is eliminated from the body. Vitamin K is
absorbed in the large intestine.
Ghrelin A hunger-arousing hormone secreted by an empty stomach
