Welcome to the fascinating world of Biology, where we delve into the intricate structures that support living organisms. In this course material, we will explore the essential topic of Tissues and Supporting Systems. This section focuses on understanding the foundational framework that provides shape, support, and coordination in both animals and plants.
One of the main objectives of this topic is to identify and explain the location and arrangement of skeletal and supporting tissues in animals. The skeletal system in animals serves crucial functions such as providing structural support, protecting internal organs, and facilitating movement. Additionally, the arrangement of tissues plays a significant role in ensuring the efficiency of bodily functions.
Another key aspect we will explore is the general plan of the mammalian skeleton and the different types of joints. Understanding the structure of the skeleton and the various types of joints is essential in comprehending how movement and flexibility are achieved in animals. From the skull to the long bones in the limbs, each skeletal component has a specific function that contributes to the overall coordination of the body.
As we progress, we will delve into the detailed study of individual bones, their functions, and how these functions are performed in coordination with muscles during movement. The relationship between the skeleton and muscles is fundamental in understanding how animals carry out activities such as walking, running, and even intricate tasks like flying in birds.
Furthermore, we will explore different types of supporting tissues in plants, such as turgid parenchyma, collenchyma, xylem, and sclerenchyma. By examining the structure and functions of these plant tissues, we gain insight into how plants maintain rigidity, transport water and nutrients, and provide support for growth and development.
To enhance your understanding, practical exercises such as cutting and drawing the low-power transverse section of a stem and root of a herbaceous plant will be included. By labeling the different tissues such as epidermis, cortex, and stele, you will gain hands-on experience in identifying and visualizing the intricate structures within plants.
By the end of this course material, you will have a deep appreciation for the interplay between tissues and supporting systems in both animals and plants. Get ready to unravel the hidden complexities that underpin the remarkable diversity of life forms on our planet.

The major buffer in blood is the **bicarbonate buffer system**. The bicarbonate buffer system maintains the pH of the blood and is integral for physiological homeostasis. This system primarily involves **bicarbonate ions (HCO3-)** and works in conjunction with carbonic acid (H2CO3).
In the blood, the bicarbonate buffer system works by a reversible chemical reaction:
CO2 + H2O ⇋ H2CO3 ⇋ HCO3- + H+
Here’s how it functions:
This system is exceptionally effective at buffering rapid changes in pH. The respiratory and renal systems support the bicarbonate buffer system. The lungs regulate the concentration of CO2, and the kidneys control the concentration of HCO3-.
While erythrocytes (red blood cells), leucocytes (white blood cells), and lymph are components of blood, they do not play a primary role in the buffering systems of blood. The bicarbonate buffer system is primarily a chemical buffer that functions independently of these cellular components.
