Flow through any vascular bed depends on its resistance to flow and the arterial pressure. As long as this pressure is maintained constant a critical point that is dependent upon adjustments in cardiac outputalterations in flow through any individual bed will have no influence on flow through other beds in parallel with it. A leaky aortic valve will cause a diastolic murmur. Normally, the aortic valve is closed during diastole when there is a large reverse pressure difference between the aorta and left ventricle.
Slowing conduction through the AV node will have no effect on the heart rate but will increase the interval between atrial and ventricular excitation. The heart rate is normally slowed by decreases in the rate of action potential initiation by pacemaker cells in the SA node. The right and left hearts are served by a common electrical excitation system and therefore beat at the same rate.
Although it is true that the right ventricle is less muscular than the left, that fact does not explain why pulmonary pressure is so low. Actually, it is the other way around: because pulmonary arterial pressure is low, the right ventricle does not have to be very muscular to pump blood into the lungs.

Circulatory System What is the circulatory system?Like the bustling factory, the body must have a transportation system to carry its various cargos back and forth, and this is where the cardiovascular system steps in. The cardiovascular system can be compared to a muscular pump equipped with one-way valves and a system of large and small plumbing tubes within which the blood travels.
The heart muscle has three layers and they are as follows:. The heart is equipped with four valves, which allow blood to flow in only one direction through the heart chambers. Although the heart chambers are bathed with blood almost continuously, the blood contained in the heart does not nourish the myocardium.
Blood circulates inside the blood vessels, which form a closed transport system, the so-called vascular system. Except for the microscopic capillaries, the walls of the blood vessels have three coats or tunics. The major branches of the aorta and the organs they serve are listed next in sequence from the heart.
Finally, the aorta passes through the diaphragm into the abdominopelvic cavity, where it becomes the abdominal aorta. Veins draining into the superior vena cava are named in a distal-to-proximal direction; that is, in the same direction the blood flows into the superior vena cava. The inferior vena cava, which is much longer than the superior vena cava, returns blood to the heart from all body regions below the diaphragm.
As the heart beats or contracts, the blood makes continuous round trips- into and out of the heart, through the rest of the body, and then back to the heart- only to be sent out again. The spontaneous contractions of the cardiac muscle cells occurs in a regular and continuous way, giving rhythm to the heart. In a healthy heart, the atria contract simultaneously, then, as they start to relax, contraction of the ventricles begin.
Cardiac output is the amount of blood pumped out by each side of the heart in one minute. It is the product of the heart rate and the stroke volume. Arterial pulse pressure and blood pressure measurements, along with those of respiratory rate and body temperature, are referred to collectively as vital signs in clinical settings. The right and left sides of the heart work together in achieving a smooth flowing blood circulation.

Specialized cell membrane structures that decrease electrical resistance between the cells allowing action potentials to pass efficiently from one cell to adjacent cells are the:. Extensive capillary network B. Intercalated disks C. Mitochondria D. Gap junctions. They directly connect the cytoplasm of two cells, which allows various molecules, ions and electrical impulses to directly pass through a regulated gate between cells.
A: Extensive capillary networks allows abundant supply of oxygen and nutrients on tissues such as skeletal muscle, liver, and kidney. They occur at the Z-line of the sarcomere and can be visualized easily when observing a longitudinal section of the tissue. Complete the diagram so that it will show the correct route of blood in the heart. Answer: D. Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium.
As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.Cardiovascular system questions and answers
When the ventricle is full, the tricuspid valve shuts. This prevents blood from flowing backward into the right atrium while the ventricle contracts. As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs, where it is oxygenated.
The oxygenated blood then returns to the heart through the pulmonary veins. The pulmonary veins empty oxygen-rich blood from the lungs into the left atrium. As the atrium contracts, blood flows from your left atrium into your left ventricle through the open mitral valve.Welcome Guest.
