Endocytosis in the body of people
who need to transport nutrients to the cells of the body, then the messenger does not want to get rid of the body, as well as other creatures
, heart
, heart and mammal species. There are similar structures
inside the heart, pericardium sac (pericardium) between both lungs. Slightly to the left slightly Within the pericardium is a fluid produced by the pericardium served lubrication. And prevent friction between the heart and lungs during heart compression of
blood vessels to the heart are called coronary heart muscle Duarte Laurie (coronary artery), which has two lines are the arteries on the left and right. It blossomed to the all parts of the heart tissue. When blood flow to the heart tissue back into the right atrium, called El preparation right (right. atrjum
heart tissue is composed of three layers, outer layer and inner layer consists of a thin epithelium. The middle layer is a thick layer of tissue of the heart muscle (cardiac. muscle)
in the circulating blood Vessels that carry blood from various parts. Of the body to the heart, called coronary events (venous blood vessel) from the heart and blood vessels that lead you to different parts. The body called Vascular Duarte Laurie (arterial blood vessel)
the right atrium or chamber's rice will get blood from a vein Bowen large 2 line is superior Web Naka wa (superior vena cava) that carry blood from the head. and arm Inphi and Maria West Bank land (inferior vena cava), which carry blood from the body and the legs to the heart. When preparing the squeeze Blood will flow into the lower right chamber of the heart called. Right ventricular (right ventricle) through the tri-lingual model closed (tricuspid valve) between the S right preparation and right ventricular. When right ventricular compression of blood flow through the valve Palomnari semiconductor Lunar (pulmomary semilunar valve) into the blood vessels Palomnari Duarte Laurie (pulmonary artery), blood vessels leading blood to the lungs for gas exchange. By releasing carbon dioxide and oxygen. Blood flow back to the heart Palomnari events (pulmonary vein) into the left atrial preparation or the left (left atrium), when preparing the squeeze. Blood flow Dubai, United tongue off (bicuspib vakve) to left ventricular or left ventricular (ieft ventricle) on left ventricular compression. The blood flows into the aorta (aorta) which aortic valve Martinez semiconductor Lunar (aorticsemilunar valve) and prevents blood flow. The aorta is the artery branching to different parts separately. Throughout the body, including the heart,
the heart function more efficiently pump blood to the heart muscle. Heartbeat caused by the contraction and relaxation of the heart muscle beat. Can measure the heart's blood vessels Duarte, Laurie called. Pulse rate This will count the number of times the heart beats in one minute a normal heart rate is 60-100 beats per minute during rhythm and stable
as muscle contraction and relaxation to change the electrical potential difference in muscle. Heart The detector can be recorded with electrocardiogram (electrocardiography) is a graph showing the effect of recording the electrocardiogram. (Eletrocardiogram) Doctors use the abbreviation ECG or EKG that we hear a typical
graph electrocardiogram, doctors will use for the detection and diagnosis of heart disease. To detect abnormalities of the heart,
heart disease is the most common. Ischemic heart disease (ischemic heart disease), most of the risk factors of high blood pressure. Have high blood cholesterol And diabetes The medical information found that people who smoke are more vulnerable to lead. Aortic stenosis and hard (Atheroslerosis) with coronary R. If the battery will result in acute myocardial infarction. Due to lack of blood supply to the heart caused by heart disease, heart valve abnormalities, such as leaks or strictures will cause problems with blood circulation. In the final stage of heart disease is the cause of heart failure is seen on a regular basis. A condition in which the heart can not be forced to send blood to nourish the body has enough to meet the body's needs at that time,
significant risk factors for heart disease include smoking, drinking and drugs. Food consumption Physical inactivity And exercises incorrectly. The frantic or stressful Therefore, students should avoid risk factors. These
arterial
blood from the heart to the blood R. Peter Larger called aorta, which has a diameter of about 2.5 cm along the Duarte Laurie small so far Duarte de Creole (. arteriole), the SR battery that has the smallest diameter 0.2 mm, and blood will flow to the capillaries, the blood vessels that connect with. Web granules (venule), which is the smallest vascular events. The blood flow to the coronary arteries Wayne Wayne, small to large. Bowen is the largest artery West Bank land (vena cava) to bring blood to the heart,
blood vessels, blood flow in different directions. Other
capillary (capillary) vessels are small, very thin walls. Consisting of a single layer membrane of epithelial tissue. Cover the external one And a diameter of about 8 microns weave gauze inserted into the tissues throughout the body
's vascular lottery. A large blood vessel wall Vascular R. battery that is big. The walls are very flexible. The aorta can be expanded to lower blood pressure, the pressure is relatively high due to the compression of the left ventricular. The contraction and relaxation of the vascular wall's battery is very sensitive to the blood pressure affects blood flow to different parts. The body's
vascular events There are three floors as well as the vascular wall R. lottery. However, there is some wall than it is less flexible. Blood pressure in coronary arteries R. Bowen under the battery
components of blood
in the body, the blood is coming.
