Notes on histology Histology Lecture 1 Histology is the study of tissues: in our case‚ it means study of tissues which make up the human body. Tissue is defined as a group of cells which perform a common function. All the cells in a given tissue are not necessarily identical or similar e.g. blood is a type of connective tissue but it has many different types of cells. However‚ tissue also contains two other components i.e. ground substance (or matrix) and fibres. Despite the complexity of

describe 2 different types of muscle in the human body Your body has lots of different vital organs which have lots of functions and are interesting in their own way. I have chosen two which I was interested in‚ including the heart and stomach. Heart The heart is a very vital organ in the body. Its job is to pump oxygenated blood throughout the body and receive deoxygenated blood back in return. The location of the heart is in the middle of the chest between the lungs. The muscle tissue of the heart is

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. The first type of tissue found

The primary xylem and primary phloem tissues are pushed inward into the] pith and outwards respectively by the continuous production of secondary tissues cut I off by the cambium ring. The primary xylem is gradually pushed inward and is found at the centre of the axis; whereas‚ the primary phloem‚ being soft in nature‚ gets completely crushed. These activities in the stelar region exert a great pressure outwardly. The cortex cells‚ the pericycle and the epidermis divide anticlinally to cope

Thousands of donated heart valves can replace damaged ones‚ allowing the heart to function well again; musculoskeletal tissue replaces bone‚ tendons and ligaments lost to cancer‚ severe trauma‚ degenerative joint disease‚ arthritis‚ and other conditions. Also‚ skin can save the lives of burn victims. "Bidding for bodies" (Dwyer) or advancing scientific research?
