PPT-Capillaries Capillaries _Are very small vessels, their diameter ranges from (4-15)Mm,

The wall of a segment of capillarity may be formed by a single endothelial cell Only tunica intimae is present which typically consist of the endothelium its basal lamina and an in complete layer of cells surrounding the capillary the pericytes . and Exchange of Materials. Learning Outcomes. Capillaries allow exchange of substances with tissues. . Pressure filtration of fluids through capillary walls. Similarity of tissue fluid and blood plasma with the exception of plasma proteins. Tissue fluid supplies cells with glucose, oxygen and other substances. Carbon dioxide and other metabolic wastes diffuse out of the cells and into the tissue fluid to be excreted . venules. , and veins differ in size, structure, and function. Kelsee. , Aimee . How it works. Blood leaves heart through pulmonary trunk and aorta. Vessels branch forming major arteries that carry blood to body organs. March . 26-27. , . 2014. Pulse Points. Areas where can easily feel pulse. Also act as . pressure points. . Compressing these points will reduce downstream blood flow . useful when dealing with major wounds.. Blood Vessels P A R T A Blood vessels and circulation Blood is carried in a closed system of vessels that begins and ends at the heart 5 types of blood vessels Arteries – carries blood away from the heart Delivery system of dynamic structures that begins and ends at the heart. Arteries: carry blood away from the heart; oxygenated except for pulmonary circulation and umbilical vessels of a fetus. Capillaries: contact tissue cells and directly serve cellular needs. What are the four main components of blood?. Describe the features of a red blood cell which aids it’s transportation of oxygen. Explain the journey an oxygen molecule takes from the alveoli to respiring tissues. The .

The . blood . vessels . that are part of the . vascularized. . It is known that the blood vessels of both the pulp and the . periodontium. arise from the inferior or superior alveolar artery and also drain by the same veins in both the mandibular and maxillary regions.

In the human . heart. there is one . atrium. and one . ventricle. for each circulation, and with both a systemic and a pulmonary circulation there are four chambers in total: . Terminology of the Blood. Blood brings oxygen and nutrients to body cells and removes waste products Whole blood is made up of plasma, which is a liquid portion, and the formed elements it contains..
