External
The circulatory system consists of three parts: the blood, the heart, and the blood vessels. T/F
False, it also consist of the lymphatic system
The circulatory system contains cell clots and proteins. T/F
False, it contains cell fragment and protein
The circulatory system distributes water through out the body to help regulate body temperature. T/F
False, it distributes heat
______________ respiration is the exchange of gases between the blood and the body's cells
Internal
Lacks a nucleus
Red blood cells
The circulatory system transports oxygen and nutrients to cells and removes waste from body cells. T/F
True
The heart pumps blood through a network of tubes inside the body called blood vessels. T/F
True
_____________ are the hearts upper chambers and _____________ are the hearts lower chambers
atria ventricles
The _________________ transmits the signal that causes both ventricles to contract.
atrioventricular node
trachea
branches into two large tubes that go to the lungs
__________________ is the mechanical movement of air into and out of the _______________
breathing lungs
_____________ are one cell thick
capillaries
Lungs excrete
carbon dioxide
arteries
carry blood away from the heart (oxygenated)
veins
carry blood to the heart (deoxygenated)
systole is when the heart ___________
contracts
When you breathe your chest cavity __________, ______________ and _____________
expands, diaphragm drops, and ribs contract
mouth or nose
filters out dust; warms and moistens air
The heart has ____ chambers
four
myocardial infarction is also known as a
heart attack
circulatory system includes....
heart, blood vessels, and respiratory system
what is the major excretory organ in the body
kidney
bronchi
large tubes that enter each lung from the trachea
heart
muscle that fills with blood and pumps blood out
The function of the respiratory system is done by supplying ____________ the cells and removing _____________ waste from the cells.
oxygen carbon dioxide
Carries glucose and fats
plasma
Clear, yellowish fluid
plasma
Releases chemicals that form fibrin
platelet
Helps clot blood
platelets
The alternating expansion and relaxation of the artery wall caused by the contraction of the left ventricle is the ___________.
pulse
transports oxygen
red blood cell
Contains hemoglobins
red blood cells
Produced in bone marrow
red blood cells White blood cells
Diastole is when the heart __________
relaxes
What are ways the excretory system helps maintain homeostasis
removing waste, carbon dioxide, salts and water maintain blood pH
The function of the respiratory system is to sustain cellular ___________
respiration
kidneys excrete
salts, water and wastes
A group of cells called the pacemaker, or ______________, in the right atrium sends out signals that tell the heart muscle to contract.
sinoatrial node
pacemaker
sinoatrial node (SA node)
bronchioles
small branches off larger tubes within each lung
The blood pressure caused by contraction of the heart is called ___________.
systole
alveoli
thin walled, individual air sacs within the lungs
capillaries
transition vessels that connect arteries to veins
Skin excretes
water and salts
fights infection
white blood cells
