First lets look at what a protist is: Protist: Any eukaryote that is not a plant, animal, or a fungus. A majority of protists are unicellular, but some are multicellular or â¦ colonial. Protists have been split into five supergroups: Excavata, Chromalveolata, Rhizaria, Archaeplastida, and Unikonta.he protists are a diverse group of eu â¦ karyotes that cannot be classified as animals, plants, or fungi. Organisms in the Protista kingdom include amoebae, red algae, dinoflagellates, diatoms, euglena and slime molds.
capillary bed small intestine â superior mesenteric vein â hepatic portal vein â liver sinusoids â hepatic vein â inferior vena cava â heart (see #1 for blood flow through heart) â systemic arteries. 4. Trace the path of a molecule of testosterone produced in the left testicle as it travels to the right atrium.
Blood flows through the right atrium into the right ventricle. The right ventricle pumps the blood to the lungs, where the blood releases waste gases and picks up oxygen. The newly oxygen-rich blood (shown in red) returns to the heart and enters the left atrium.he tricuspid valve connects the right atrium with the right ventricle. The semilunar valves allow the blood to flow out of the heart into the 2 main arteries (aorta and pulmonary artery). They prevent blood from returning to the heart. The top of the heart connects to a few large blood vessels.
