Cardiovascular

QuestionAnswer
Blood vessels that deliver blood from the heart to other parts of the body. They have a thick layer of smooth muscle in their walls to withstand the pressure of the forceful heartbeat. Arteries
Small blood vessels that connect arterioles to venules, only one cell thick. Capillary
The portion of the cardiac cycle in which the heart refills with blood, a rest phase, when the chambers relax and refill. Diastole
The muscle that pumps blood throughout the body The heart
The protein in red blood cells that carries oxygen from the lungs to the rest of the body Hemoglobin
White blood cells, which protect the body against disease leukocyte
A sub-type of white blood cell found in lymph Lymphocyte
The pale yellow component of blood that carries red blood cells, white blood cells, and platelets throughout the body Plasma
The portion of the cardiac cycle in which the heart expels blood, when a contraction happens. Systole
Blood vessels that carry blood to the heart. They are connected to the capillary beds via smaller branches called venules. Vein
The "BLANK" system is responsible for the movement of blood and lymph around the body, which permits nutrient distribution, waste removal, communication, and protection. Cardiovascular, or circulatory,
The _ comprises the closed system of blood pumped around the body by the heart through a network of _ , ___, ____ as well as the open _____ , comprises _____ that bathes the interstitial spaces between cells and circulates through lymph vessels. The circulatory system; arteries, veins, and capillaries; lymphatic system; lymph
The cardiovascular system is made of four main components: the heart, blood vessels, blood, and lymphatic system.
The heart is a large muscular organ comprised of cardiac tissue called "BLANK" and is surrounded by a sac called the "BLANK" myocardium. pericardium
The heart contains four chambers divided by a "BLANK" median septum
The"BLANK" are the receiving chambers and the "BLANK" are the pumping chambers. two superior atria, two inferior ventricles
The atria and ventricle are separated by the Atrioventricular valves.
The right side of the heart pumps "BLANK" blood from the heart toward the lungs and is called the "BLANK" deoxygenated; pulmonary system.
The left side of the heart receives "BLANK" blood from the lungs and pumps it toward the rest of the body parts and is known as the"BLANK" . oxygenated; systemic system.
The larger arteries branch into increasingly smaller"BLANK" which eventually connect to a bed of "BLANK". arterioles, capillaries
Exchange of gases and nutrients occurs between the alveoli of lungs and the Capillary beds of the cardiovascular system.
"BLANK" and "BLANK" thinner walls because they are farther from the force of the heartbeat and so experience less pressure on their walls. Veins and venules
Veins have "BLANK" to prevent blood from flowing back into the system. one-way valves
Blood is composed of Plasma and formed elements
The formed elements are the Erythrocytes (red blood cells), leukocytes (white blood cells), and platelets.
The "BLANK" are responsible for the clotting mechanism. Platelets
The lymphatic vessels are linked to Lymph nodes and lymphatic capillaries.
"BLANK" are thin-walled and contain one-way valves to maintain flow in one direction only. Lymph vessels
Lymphatic capillaries are entwined with cardiovascular capillaries they Absorb excess tissue fluid and blood plasma that leaks from the capillaries
lymph fluid is filtered through hundreds of small organs called "BLANK" distributed throughout the body. Lymph nodes
Lymph nodes are concentrated in the neck, armpit, and groin, and contain "BLANK" which seek out pathogens in the fluid. Lymphocytes
The lymphocytes make "BLANK" , which target the pathogens so that other cells can destroy them. Antibodies
The filtered lymph fluid is essentially “cleaned” "BLANK" and is returned to the "BLANK" via the "BLANK" Blood plasma, cardiovascular system , veins
The heartbeat is also known as the Cardiac cycle
The cardiac cycle begins with the triggering of an impulse within "BLANK" known as the pacemaker, which is located "BLANK" The sinoatrial (SA) node, in the upper wall of the right atrium
After going to the SA node impulse spreads to "BLANK" causing them to contract and forcing blood into the ventricles. The right and left atria.
After the impulse reaches the right and left atria, it goes to the "BLANK" also in the right atrial wall, and travels along the "BLANK" down the right and left branches in the Atrioventricular (AV) node, atrioventricular bundle, septum
After it goes through the septum, finally along the "BLANK" in the walls of the ventricle, causing the filled ventricles to contract. Purkinje fibers
External control of the heart is managed in the "BLANK" and modulated by the hormones "BLANK" and "BLANK" cardiac center of the brain, epinephrine and norepinephrine.
Blood pressure is measured in "BLANK" and expressed as the "BLANK" , with an expected average reading of 120/70 mm Hg millimeters of mercury (mm Hg), maximum pressure over the minimum pressure
The "BLANK" of the heart causes the blood to push against the muscular walls of the arteries to a maximum pressure. contraction (systole)
When the heart "BLANK" , the elasticity in the vessel walls recoils and the pressure decreases to a minimum. relaxes (diastole)
This disease cause rupture of the smaller arterioles and capillaries possibly leading to a stroke. High blood pressure (hypertension) can
"BLANK" is a buildup of plaque in blood vessels that reduces the flow of blood through the vessel. Atherosclerosis
A piece of plaque or clotted blood traveling through vessels is known as an embolus.
A "BLANK" occurs when the normal blood flow to the brain is stopped either by a blockage or by a rupture of a blood vessel, causing death of brain tissue stroke
A "BLANK" , occurs when the flow of blood to a part of the heart muscle is blocked, causing cardiac muscle tissue to die. heart attack or myocardial infarction,
