CAPILLARIES IN WEB OF FROG'S FOOT According to the law of volume flow, the amount of blood flowing through the combined capillaries in a unit of time is the same as that passing through the aorta (if measured over a considerable length of time).

Dec 15, 1975 · The flow velocity profile in the venule of frog web was measured by using a laser Doppler microscope of a crossed-beam which permitted a measurement of flow velocity in a clearly defined small volume.

Study with Quizlet and memorize flashcards containing terms like Explain the functional significance of the differences you noted in the structures of the arterial and venous walls, How did you distinguish arterioles and venules when you observed the vessels in the web of the frog's foot?, How did you recognize capillaries in the web? and more.

Sep 1, 2014 · Blood flowing in capillaries in the web of juvenile clawed toads. the dark spots are melanocytes. When expanded, these pigmented cells darken the skin which is otherwise rather tarnsparent.

The flow velocity profile in the venule of frog web was measured by using a laser Doppler microscope of a crossed-beam which permitted a measurement of flow velocity in a clearly defined small volume.

Jan 22, 2018 · Identifying species by sight can be tricky. In this image, five of the frogs are the same species of grass frog, “Ptychadena porosissima,” according to DNA barcoding, while one, in the bottom center, is actually a different species, “Ptychadena taenioscelis.”

Studies on the physiology of capillaries: II. The reactions to local stimuli of the blood-vessels in the skin and web of the frog

Frog dissection handout describes how to dissect a frog and locate structures. Covers major organ systems and has several diagrams to label and questions.
