Hello Rittika meli pyali pyali behna ❤️❤️☺️

☛Have your answer plzzzzzzz.....☺️☺️

==================================
It is a S-shaped graph that is why it is known as "SIGMOID GRAPH".
It is the graph which represents the percentage of saturation of hemoglobin with O2 against the PO2.
As shown in figure.... above.
***********************************************

◼️Right shift of curve :---
=====================
It indicates that the hemoglobin under study has a decreased affinity for O2.

◼️Left shift of curve :---
======================
It indicates that the hemoglobin's increased affinity for the O2 in the lungs.

=================================
◼️1.) Temperature :---
====================
a.) Increased in temperature will shift the curve to the right.
b.) Decreased in temperature will shift the curve to the left.

◼️2.) BPG ( Bisphosphoglyceric acid ) :--
=================================
Increased in RBCs, increases the formation of T, low affinity state of hemoglobin and so that O-binding curve will shift to the right and vice versa.

◼️3.) pH of blood :----
====================
a.) pH increased will shift the curve to the Left.
b.) pH decreased will shift the curve to the right.

◼️4.) H+ ions :----
=================
a.) Increased in the concentration of H+ ions in blood, shifts the curve to the right.
b.) Decreased in concentration of H+ ions in blood, shifts the curve to the left.

◼️5.) PCO2 ( Partial perssure of CO2 ) :----
=================================
a.) Increased in PCO2, will shift the curve to the right.
b.) Decreased in PCO2, will shift the curve to the left.

Hope it will help you Rittika ☺️♥️

Thanks sistah!!!

Explanation:

The oxygen–hemoglobin dissociation curve, also called the oxyhemoglobin dissociation curve or oxygen dissociation curve (ODC), is a curve that plots the proportion of hemoglobin in its saturated (oxygen-laden) form on the vertical axis against the prevailing oxygen tension on the horizontal axis.

This curve is an important tool for understanding how our blood carries and releases
