ventricle influence the function of the other. The pericardium plays a pivotal role in cardiac changes during inspiration. Normally‚ as the right atrium and ventricle fill during inspiration‚ the pericardium limits the ability of the left-sided chambers to dilate. This contributes to the bowing of the atrial and ventricular septums to the left‚ which reduces left ventricular (LV) filling volumes and leads to a drop in cardiac output. As intrapericardial pressures rise‚ as occurs in the development of a pericardial

Histology This lab focused on the examination and identification of tissues that make up the organs of the body. The tissues are divided into four main categories: epithelial‚ connective‚ muscle‚ and neuronal. Click on the thumbnail images to see a larger version. All of the photomicrographs were taken using the 40X objective (400X magnification)‚ which is the highest magnification we use in this lab. Other resources include linked web pages on the "Resources" page and the histology tutorial

P2: Outline the structure of the main tissues of the body. In this assignment I’m going to talk about the structure of the main tissues which are found within the body as well as what their role is in the terms of two named organs of the body. Tissues are a collection of similar cells that group together to carry out a specific function within the body. There are four different types of tissue found in the human body which include; epithelial tissue; connective tissue; muscle tissue and nerve tissue

They are three basic kinds of muscle tissue- Skeletal‚ smooth and cardiac muscle. Smooth a d Cardiac muscle occurs with other tissue that forms organs such as a bladder and the heart. Skeletal muscle makes up the muscular system‚ which interacts with the skeleton to move our body parts the muscle of the body enables individuals to stand

PERICARDITIS The heart is a strong muscular organ that is responsible for sustaining life. During the course of the lifespan‚ many different types of illness or injury can interfere with the heart and its functioning. The heart is located within a sac‚ a double layered‚ flexible holding vessel that is named the pericardium. The pericardium is responsible for keeping the heart in the proper place. It is also the reason that the heart does not fill with more blood than it can hold. This
