Circulatory System of Frogs vs. Circulatory System of Humans The circulatory system of a human compared to that of a frog is different due to the number of chambers each contains. A frog’s heart has three chambers (two atria‚ and a single ventricle)‚ whereas a human’s has four (two atria‚ and two ventricles). The atrium of a frog receives deoxygenated blood from the blood vessels that drain the various organs of the body. The left atrium receives oxygenated blood from the lungs and skin. Both

Compare and contrast cardiac and smooth muscle. In cardiac muscle‚ each heartbeat is triggered by the hearts own pacemaker cells‚ which initiate electrical discharge and when this reaches the contractile muscle cells (the cardiomyocytes)‚ they create an action potential which increases the concentration of calcium ions into the cell. Calcium ions play a key role in activating what is known as the contractile machinery – the actin and myosin filaments. The cardiac action potential‚ unlike other forms

In “The Notorious Jumping Frog of Calaveras County”‚ Mark Twain specifically uses this story to describe people. In this story‚ he uses details about people. If someone pronounces something different‚ he spells the word with how they pronounced it. Twain’s character‚ Simon Wheeler‚ uses pronunciation this way. Twain uses a lot of details to describe the characters. Simon is “fat and baldheaded” and another character‚ Jim Smiley‚ is “always betting on anything”. All the main characters are described

Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences

Purpose Name Due Date Clothespin Lab / Muscle Fatigue What are the affects of anaerobic respiration on you muscles? Background Normally‚ muscles use oxygen through a process known as cellular/aerobic respiration to make energy (or ATP) from sugar (glucose). This process is very efficient and produces 38 ATPs for each molecule of glucose. Carbon dioxide and water are the results of this reaction. When muscles undergo rigorous exercise they require more oxygen to make ATP than the
