The septum form is that ist a wall that divides the left side of the heart from the right side. This keeps the deoxygenated blood from mixing with the oxygenated blood. With the septum having the function of being like a wall it allows it to keep its function of being a barrier between the left and right side of the heart. Respiratory The lungs form is pretty much a sac that is like a balloon. It is flexible in order to inflate and deflate. The lung being like a balloon and flexible allows it to

What are bodily systems?- Bodily systems are basically default programmes within our body that pickup information from within or the external environment and trigger an automated response. For example if you were to run‚ your body would increase its heart rate to match the oxygen demand made by the muscles. This is done without thinking and it is made possible by how the brain has cleverly integrated with all the bodily systems‚ from the digestive system to the circulatory system. It is critical

Introduction: Crayfish also known as Procambarus clariia are classified as a decapod crustaceans related to lobsters‚ crabs‚ and shrimp. They breathe through the gills as they are aquatic animals but they can survive for short time outside the water. They have a hard‚ calcified exoskeleton that must be shed as they grow. In front of the first abdominal segment locates crayfish heart in the dorsal portion of cephalothorax. Crayfish are poikilothermic as their internal temperature is proportional

Penguins have evolved in a complex and distinguishably different manner than most birds. This style of evolution raises uncertainty about their future. Unlike most birds‚ which have flexible elbow joints and wings for flight‚ penguins have evolved with virtually inflexible elbow joints and flippers with a hydrofoil shape‚ which allows them to propel underwater. Furthermore‚ penguins have short stalky legs and broad anklebones‚ which allow them to maneuver in water and have an energy efficient waddle

Measuring blood pressure has been an evolutional process in medical history. The results of a blood pressure can be indicative of many things. It plays a very important role in the health care management of individuals. Exercise is a great way to manage blood pressure levels and to keep them within optimal range. However‚ immediately after exercise it can be slightly elevated. Pulse pressure‚ heart rate and mean arterial pressure are also considered. The results varied depending on the individual

The purpose of this lab was to determine how different conditions could affect one’s heart rate. In the life of a human‚ the heart beats approximately forty-five million times per year varying based off of factors like age‚ gender‚ physical activity level (1). Furthermore‚ throughout the course of a day‚ the heart can vary in its heart rate from a number of different environmental changes such as prolonged standing‚ altered breathing (inhale vs. exhale)‚ and jolts of excitement such as being startled

INTRODUCTION: The purpose of the “Blood Pressure and Pulse Experiment” is to determine how postural changes‚ exercise and cognitive stressors affect blood pressure and heart rate. Background The pressure of blood in the circulatory system is‚ also known as blood pressure (BP) is “the force exerted on a vessel wall by contained blood. This is expressed in millimeters per mercury (mmHg)” (Marieb & Hoehn‚ 2016‚ pp. 708). There are two parts to blood pressure: systolic pressure and diastolic pressure

Introduction: The cardiovascular system is composed of blood vessels‚ blood‚ and the heart. This allows the system to play an important role in the moving of both nutrients and wastes in and out of the blood to maintain an overall homeostasis within the body. The previously completed experiments each had the objective of understanding how various factors may have an influence on blood flow rate. These factors include the effect of blood vessel radius‚ the effect of blood viscosity‚ as well as
