    Transcript

    00:01 So to conclude our lecture on blood vessels, recall that the blood vessels in the body work with our lymphatic vessels to circulate fluids.

    00:11 There are three types of blood vessels in the body: arteries, veins, and capillaries.

    00:17 Structurally, blood vessels contain three tunics: the tunica intima, the tunica media, and the tunica externa.

    00:27 Capillaries are microscopic blood vessels associated with our tissues.

    00:32 This is where nutrient exchange occurs.

    00:36 They contain fenestrations and/or intracellular clefts that make them leaky.

    00:43 The arteries are high-pressure vessels, while our veins are going to be low pressure vessels.

    00:50 Blood Pressure is a measure of the pressure that blood exerts on the walls of our blood vessels.

    00:57 Blood pressure and flow is related to cardiac output, peripheral resistance, and our blood volume.

    01:06 Blood Pressure is regulated by hormonal, neural, and renal controls.

    01:12 At the capillaries, fluid and molecule movement can be driven by bulk flow, and both osmotic and hydrostatic pressures.

    01:22 And finally, the circulatory pathways of the body include the pulmonary and systemic circulation.

    01:30 This concludes our lecture on the blood vessels.

    01:33 Thank you for listening.
