1. Point A is considered the S1 area of the graph. At this point in the graph is where the sound “lubb” is heard. At this point is when the AV closes and the semilunar valve closes.
2. Point D is at the S2 area. This is where the “dub” sound is made. This is the beginning of ventricular filling where the AV valves open.
3. At the end of the atrial systole, the ventricles have a maximum amount of blood that each can carry. The quantity of this is known as the end- diastolic volume.
4. In S2 is the occurrence of ventricular filling, when the semilunar vale closes and the AV valve opens.
5. Red Blood Cells have a protein, which is hemoglobin, oxygen binds to the hemoglobin and is transported from the lungs to the cells throughout the body. …show more content…
Cardiac output is the amount of blood pumped through the left ventricle per unit. This is found by multiplying the heart rate and stroke volume. Increasing the heart rate would increase the cardiac output. Sympathetic stimulation releases NE and this shortens repolarization and speeds up depolarization, which increase heart rate. An increase in venous return causes the heart rate to increase by stretching the nodal cells, and the force of contraction increase, and this increases the stroke volume. The parasympathetic stimulation releases ACh, which slows down the heart rate.
21. If hemorrhaging occurs, there are two major effects. Venoconstriction occurs, which decreases the amount of blood in the venous system and increases blood in the arterial and capillary systems. A circulation called venous reserve occurs, which is, when blood flow to delicate organs and active skeletal muscles can be increased or maintained after blood loss. Peripheral vasodilation on the other hand widen blood vessels on body parts such as the arms and …show more content…
The right atrium gets blood from the systemic circuit and passes it to the right ventricle and it pumps blood to the pulmonary circuit. The left atrium collects blood from the pulmonary circuit and empties it into the left ventricle which then pumps blood into the systemic circuit.
39. Pericardial inflammation results in a production of pericardial fluid. The fluid builds u in the pericardial cavity, which restricts movement of the heart, and this is known as cardiac tamponade. In contrast, pericarditis is when pathogens infect the pericardium and causes inflammation.
40. The right atrium receives blood from the systemic circuit from two great veins, the superior vena cava and the inferior vena cava. The coronary sinus opens into the right atrium inferior to the connection with the superior vena cava.
41. ADH is released at the posterior lobe of the pituitary glands. It causes a peripheral vasoconstriction that elevates blood. This hormone stimulates water conservation by the kidney which would prevent reducing blood volume.
43. In rapid depolarization in cardiac muscle, at threshold, it has a voltage gated sodium channel open and the membrane becomes permeable to Na+.
44. Gloubins are the second most abundant plasma protein. A plasma gloubin, immunogloubins, assist in body defense. In contrast fibrinogens assist in
